Project description:Centromeres are chromosomal regions that serve as platforms for kinetochore assembly and spindle attachments, ensuring accurate chromosome segregation during cell division. Despite functional conservation, centromeric sequences are diverse and usually repetitive across species, making them challenging to assemble and identify. Here, we describe centromeres in the model oomycete Phytophthora sojae by combining long-read sequencing-based genome assembly and chromatin immunoprecipitation for the centromeric histone CENP-A followed by high-throughput sequencing (ChIP-seq). P. sojae centromeres cluster at a single focus in the nucleus at different life stages and during nuclear division. We report a highly contiguous genome assembly of the P. sojae reference strain, which enabled identification of 15 highly enriched CENP-A binding regions as putative centromeres. By focusing on 10 intact regions, we demonstrate that centromeres in P. sojae are regional, spanning 211 to 356 kb. Most of these regions are transposon-rich, poorly transcribed, and lack the euchromatin mark H3K4me2 but are embedded within regions with the heterochromatin marks H3K9me3 and H3K27me3.

Project description:This experiment contains Phytophthora sojae samples and RNA-seq data from experiment E-GEOD-29561 (https://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-29651/) to understand gene expression during the P. sojae life cycle. The transcriptome of the oomycete plant pathogen Phytophthora sojae was profiled at 5 different developmental stages: mycelia (MY), zoosporangia (SP), zoospores (ZO), cysts (CY) and germinating cysts (GC); based on a 3'-tag digital gene expression (DGE) protocol. More than 90 million clean sequence tags were generated and compared to the P. sojae genome and its 19,027 predicted genes. A total of 14,969 genes were detected, of which 10,044 were deemed reliable because they mapped to unambiguous tags. A web-based server named the Phytophthora Transcriptional Database (PTD) has been established.

Project description:Plant pathogens secreted effector proteins to overcome host immunity system and gain access to colonization. Although more than 300 hundred of RxLR effectors were encoded by the devastating soybean pathogen Phytophthora sojae, the patterns of conditionally expressed effector genes were well programmed. However, the effector gene regulation mechanisms were not fully dissected. In this study, we identified the H3K36me3 methyltransferase PsKMT3. Phenotypic assays showed PsKMT3 was involved in regulation of growth, sporulation, zoospore production and pathogenicity. ChIP-seq analysis, together with RNA-seq analysis, showed PsKMT3 controlled a set of RxLR gene expression. The transcriptome comparison showed large-scale mis-expression of RxLR waves during mycelium, 3 hpi and 6 hpi stages between WT and pskmt3. Our result supports a new RxLR gene regulation mechanisms in which methyltransferase PsKMT3 maintains well programmed RxLR gene expression in P. sojae.
